Abstract
The invention relates to the technical field of metal cutting fluid, in particular to metal cutting fluid and a preparation method thereof. The metal cutting fluid comprises the following components in percentage by mass: 12% -18% polyethylene glycol; 2% -6% of phenethyl phenol polyoxyethylene ether; 3% -5% of antirust agent (modified antirust agent, benzotriazole and barium petroleum sulfate are mixed according to the proportion of 1: 1.2: 1); 1.0-1.2% of a hard water resistant agent; 0.5% -1.2% of a bactericide; 2% -5% of a defoaming agent; 0.2% -0.5% of preservative; the balance being solvent. The invention has the following beneficial effects: has better rust resistance. In addition, the phenomenon that the metal cutting fluid is not smelly after being uncovered can be effectively prevented, and the service life is long.
Description
Technical Field
The invention relates to the technical field of metal cutting fluid, in particular to metal cutting fluid and a preparation method thereof.
Background
In the process of cutting, cutting and grinding metal, the cutting tool needs to be cooled and lubricated by using metal cutting fluid so as to prevent poor cutting effect caused by overheating of the cutting tool due to friction.
At present, domestic metal cutting fluid comprises oil-based cutting fluid which has good lubricating property but poor cooling effect, and generates smoke and pollutes the environment at high temperature of cutting. In order to reduce this problem, water-based cutting fluids are currently on the market, which have good cooling properties, high fire resistance, and little environmental pollution, and thus are widely used.
Chinese patent No. CN103436343B discloses a metal cutting fluid, which comprises sorbic acid, 2%; sebacic acid, 2%; diethanolamine, 25%; 5% of triethanolamine; 1% of sodium molybdate; 0.5 percent of boric acid; SDT-06E, 5%; 0.1 percent of benzotriazole; 1% of monoethanolamine; 3% of sodium nitrite; the balance being water. However, sodium nitrite is used as an antirust agent, toxic hydrogen sulfide is produced by S element and saponified substance due to high temperature generated by cutting, and sodium nitrite is harmful to human body. Therefore, a metal cutting fluid which is more environment-friendly, antirust and good in cooling property is needed.
Disclosure of Invention
The invention aims to provide a metal cutting fluid, which mainly aims to provide the antirust property of the metal cutting fluid in the prior art and ensure that the metal cutting fluid is more environment-friendly.
The above object of the present invention is achieved by the following technical solutions: the metal cutting fluid consists of the following components in percentage by mass:
12% -18% polyethylene glycol;
2% -6% of phenethyl phenol polyoxyethylene ether;
3% -5% of antirust agent (modified antirust agent, benzotriazole and barium petroleum sulfate are mixed according to the proportion of 1: 1.2: 1);
1.0-1.2% of a hard water resistant agent;
0.5% -1.2% of a bactericide;
2% -5% of a defoaming agent;
0.2% -0.5% of preservative;
the balance being solvent;
the modified antirust agent is prepared by the following steps:
s 1: preparing raw materials, dissolving 20 parts by weight of boric acid into glycerol to form a saturated solution, heating 25 parts by weight of triethanolamine oil bath to 100 ℃, preserving heat for 0.5h, and soaking 2-5 parts by weight of cation exchange resin into normal-temperature deionized water for 24h for later use.
s2, adding the triethanolamine into cation exchange resin, adding 5 parts of boric acid glycerol saturated solution into the triethanolamine for 4 times, heating to 140 ℃, keeping the temperature for 4 hours, and stopping reaction to obtain the required modified rust remover;
s 3: filtering, and separating the cation exchange resin from the obtained modified rust remover.
By adopting the technical scheme, the polyethylene glycol is used as the lubricant, so that the lubricity of the metal cutting fluid can be effectively improved, the phenethyl phenol polyoxyethylene ether is used as the surfactant, so that oil stains on a machine tool stained on the surface of metal can be cleaned during metal cutting, and the phenethyl phenol polyoxyethylene ether can enhance the dispersion of the antirust agent. The modified antirust agent is composed of triethanolamine borate, which is formed by esterifying boric acid and triethanolamine, and is prepared by dissolving boric acid in water and then adding toluene or strong acid for reaction in a common esterification reaction, but the boric acid has low solubility in water and is difficult to dissolve, and in addition, the toluene and the strong acid are used as catalysts to pollute the environment, so that the boric acid is dissolved by adopting glycerol to dissolve the boric acid as much as possible and then reacts with the triethanolamine. Before the cation exchange resin is used, it needs to be activated, i.e. it needs to be put into deionized water for 24 h. The modified antirust agent prepared by the method has high yield and is green and environment-friendly in the production process.
